VkExternalMemoryBufferCreateInfo

Specify that a buffer may be backed by external memory

To define a set of external memory handle types that may be used as backing store for a buffer, add a VkExternalMemoryBufferCreateInfo structure to the pNext chain of the VkBufferCreateInfo structure. The VkExternalMemoryBufferCreateInfo structure is defined as:

typedef struct VkExternalMemoryBufferCreateInfo {
    VkStructureType sType;
    const void* pNext;
    VkExternalMemoryHandleTypeFlags handleTypes;
} VkExternalMemoryBufferCreateInfo;

or the equivalent

typedef VkExternalMemoryBufferCreateInfo VkExternalMemoryBufferCreateInfoKHR;

A VkExternalMemoryBufferCreateInfo structure with a non-zero handleTypes field must be included in the creation parameters for a buffer that will be bound to memory that is either exported or imported.

  • sType is a VkStructureType value identifying this structure.
  • pNext is NULL or a pointer to a structure extending this structure.
  • handleTypes is zero or a bitmask of VkExternalMemoryHandleTypeFlagBits specifying one or more external memory handle types.

Valid Usage (Implicit)

VUID-VkExternalMemoryBufferCreateInfo-sType-sType

sType must be VK_STRUCTURE_TYPE_EXTERNAL_MEMORY_BUFFER_CREATE_INFO

VUID-VkExternalMemoryBufferCreateInfo-handleTypes-parameter

handleTypes must be a valid combination of VkExternalMemoryHandleTypeFlagBits values
